So, it is getting warm outside ...
.................................................and
........................................................inside!

Our answer to the problem; design our own ac with items we already have.

Materials:

• one large styrofoam cooler
• two elbow dryer vents
• one small but powerful fan
• many jugs of frozen water
• knife for cutting
• mini vacuum for clean-up

The plan:

1. line up the fan and dryer vents on the cover to see how they will all fit
2. trace the items carefully and closely on the lid
3. remove the items and prepare to cut
   *it is important to cut slowly and carefully
   *cut straight down
   *cut right into the inside of the traced line for the dryer vents
   *cut 1 to 2 cms into the circle of the traced outline for the fan -
   the fan doesn't fit into it but rather rests on top of the styrofoam lid
4. vacuum away the small particle of styrofoam
5. place your frozen bottles into the cooler
6. press the dryer vents into the holes
7. rest the fan facing down into the cooler
8. start your engine
